Can't make Admob App Open Ads to appear on app launch

I'm trying to implement Admob App Open Ads and did exactly what it says on Admob page. But ad doesn't open on app launch but it opens on if app minimized to background and bring back to foreground. I think this is the default Google implementation of app open ads. But I want to make app appear on app launch. Can you help me?
There is 2 classes that makes app open ads work. MyApplication and AppOpenManager classes.
public class MyApplication extends Application {
private static AppOpenManager appOpenManager;
#Override
public void onCreate() {
super.onCreate();
MobileAds.initialize(
this,
initializationStatus -> {});
appOpenManager = new AppOpenManager(this);
}
}
and

private static boolean isShowingAd = false;
/**

Google consent SDK

I try to use Google ConsentSDK to show in Android app consent form.
When I call form.show() I get this error:
"Consent form error Consent form is not ready to be displayed."
Who can help me?
My code:
ConsentForm form = new ConsentForm.Builder(context, privacyUrl)
.withListener(new ConsentFormListener() {
#Override
public void onConsentFormLoaded() {
// Consent form loaded successfully.
Log.d("SplashScreen", "Consent form Loaded ");
}
#Override
public void onConsentFormOpened() {
// Consent form was displayed.
Log.d("SplashScreen", "Consent form opened ");
}
#Override
public void onConsentFormClosed(
ConsentStatus consentStatus, Boolean userPrefersAdFree) {
// Consent form was closed.
Log.d("SplashScreen", "Consent form Closed ");
}
#Override
public void onConsentFormError(String errorDescription) {
// Consent form error.
Log.d("SplashScreen", "Consent form error " + errorDescription);
}
})
.withPersonalizedAdsOption()
.withNonPersonalizedAdsOption()
.build();
form.load();
form.show();

Here is my helper class for the Google Consent SDK that I use in my app. To initialise the consent information and display the Consent Form if needed, I have following code in onCreate() method of my main activity:
GdprHelper gdprHelper = new GdprHelper(this);
gdprHelper.initialise();
Similarly, I run following code when user clicks on "Reset my privacy consent" in preferences:
GdprHelper gdprHelper = new GdprHelper(this);
gdprHelper.resetConsent();
where both times, this is referencing current running activity.
Full implementation of the helper class:
package com.example.app;

private static final String MARKET_URL_PAID_VERSION = "market://details?id=com.example.app.pro";
private final Context context;
private ConsentForm consentForm;
public GdprHelper(Context context) {
this.context = context;
}
// Initialises the consent information and displays consent form if needed
public void initialise() {
ConsentInformation consentInformation = ConsentInformation.getInstance(context);
consentInformation.requestConsentInfoUpdate(new String[]{PUBLISHER_ID}, new ConsentInfoUpdateListener() {
#Override
public void onConsentInfoUpdated(ConsentStatus consentStatus) {
// User's consent status successfully updated.
if (consentStatus == ConsentStatus.UNKNOWN) {
displayConsentForm();
}
}
#Override
public void onFailedToUpdateConsentInfo(String errorDescription) {
// Consent form error. Would be nice to have proper error logging. Happens also when user has no internet connection
if (BuildConfig.BUILD_TYPE.equals("debug")) {
Toast.makeText(context, errorDescription, Toast.LENGTH_LONG).show();
}
}
});
}
// Resets the consent. User will be again displayed the consent form on next call of initialise method
public void resetConsent() {
ConsentInformation consentInformation = ConsentInformation.getInstance(context);
consentInformation.reset();
}
private void displayConsentForm() {
consentForm = new ConsentForm.Builder(context, getPrivacyUrl())
.withListener(new ConsentFormListener() {
#Override
public void onConsentFormLoaded() {
// Consent form has loaded successfully, now show it
consentForm.show();
}
#Override
public void onConsentFormOpened() {
// Consent form was displayed.
}
#Override
public void onConsentFormClosed(
ConsentStatus consentStatus, Boolean userPrefersAdFree) {
// Consent form was closed. This callback method contains all the data about user's selection, that you can use.
if (userPrefersAdFree) {
redirectToPaidVersion();
}
}
#Override
public void onConsentFormError(String errorDescription) {
// Consent form error. Would be nice to have some proper logging
if (BuildConfig.BUILD_TYPE.equals("debug")) {
Toast.makeText(context, errorDescription, Toast.LENGTH_LONG).show();
}
}
})
.withPersonalizedAdsOption()
.withNonPersonalizedAdsOption()
.withAdFreeOption()
.build();
consentForm.load();
}
private URL getPrivacyUrl() {
URL privacyUrl = null;
try {
privacyUrl = new URL(PRIVACY_URL);
} catch (MalformedURLException e) {
// Since this is a constant URL, the exception should never(or always) occur
e.printStackTrace();
}
return privacyUrl;
}
private void redirectToPaidVersion() {
Intent i = new Intent(
Intent.ACTION_VIEW,
Uri.parse(MARKET_URL_PAID_VERSION));
context.startActivity(i);
}
}

Ok I solved this way: create an instance of your form with the Builder and then you have to call the form.load().
Wait for the form to be loaded and call the .show() inside:
#Override
public void onConsentFormLoaded() {
// Consent form loaded successfully... now you can show it.
Log.d("SplashScreen", "Consent form Loaded ");
showConsentForm();
}
To accomplish this I created a private function :
private showConsentForm(){ form.show(); }
To see how the form works you can try this app:
https://play.google.com/store/apps/details?id=com.mapkcode.whereis

The simple answer is that the form cannot be shown until the form has completed loading. The docs on this nuance are rather dreadful. The fix is to call form.show() within onConsentFormLoaded() like this:
public class MyGdprHelper {
private ConsentForm form;
private void getUsersConsent() {
form = new ConsentForm.Builder(context, privacyUrl)
.withListener(new ConsentFormListener() {
#Override
public void onConsentFormLoaded() {
// Consent form loaded successfully.
form.show();
}
#Override public void onConsentFormOpened() {...}
#Override public void onConsentFormClosed(ConsentStatus consentStatus, Boolean userPrefersAdFree) {...}
#Override public void onConsentFormError(String errorDescription) {...}
)
.withPersonalizedAdsOption()
.withNonPersonalizedAdsOption()
.withAdFreeOption()
.build();
form.load();
}
...
}

How to detect if it is Recents button, Multi Window mode or home button onUserLeaveHint()

In my app, I am relying on onUserLeaveHint() method when the user presses the home button, but this method is also being called when you are starting multi window mode in android 7.0 by long pressing "recents button" (which I don't want to perform same thing that I do when home button been pressed). So I want to know if there is a way to detect which is which. Cheers!
Note: onMultiWindowModeChanged() being called after onUserLeaveHint()

I think this is what you're looking for.
HomeWatcher mHomeWatcher = new HomeWatcher(this);
mHomeWatcher.setOnHomePressedListener(new OnHomePressedListener() {
#Override
public void onHomePressed() {
// do something here...
}
#Override
public void onHomeLongPressed() {
}
});
mHomeWatcher.startWatch();

Google recognizer and pocketsphinx in two different classes, how to loop them?

Yesterday i ask a simplified question of my problem, but think its too simplified.
What my programm should do, is to hear a keyword and when he hear it, he should listen to what i said. (like if you told to siri or google now, by saying siri or ok google).
I'm using pocketsphinx for the keyword and the google speechrecognizer for the longer parts. It works, but only for one time. The pocketsphinx is in the MainActivity and the google recognizer is in an extra class (Jarvis).
The programm starts with the pocketsphinx listener, when he hear the KEYPHRASE, he starts the google listener by calling jarvis.startListener() (by the next()-method) and there is the problem, when the googlelistener is done, i dont come back from the Jarvis-class to the MainActivity to call the next() method again.
(when the google recognizer is done, the last things he do is in the onResult() in Jarvis-class, but from there i cant call the next()-method from MainActivity-class)

You can store reference to the main activity in Jarvis object in a field:
class Jarvis {
....
private MainActivity m;
....
public Jarvis(MainActivity m) {
this.m = m;
}
....
public void onResults(Bundle results) {
....
m.next();
}
You can also send intents to the main activity as described here. This might be overkill in your case though.

how to call onOptionsItemSelected on a different activity

I have an activity with uses onOptionsItemSelected(MenuItem item) method in FolderActivity and I want to call this method on another activity (MainActivity)
the main activity uses CMU Sphinx - Speech Recognition Toolkit.
I need to call some methods from FolderActivity to MainActivity.

the FolderActivity runs on top of the MainActivty but the voice recognition in MainActivity is still active and I want the voice itself do some manipulation in the FolderActivity

Here's a few suggestions:
Have FolderActivity register a BroadcastReceiver as a listener for a certain Intent. When MainActivity wants to do something in FolderActivity, it can send a broadcast Intent which will be seen by the BroadcastReceiver in FolderActivity, which can then call the appropriate method in the `Activity.
When MainActivity wants to do something in FolderActivity, it can launch FolderActivity again using an Intent with flag Intent.FLAG_ACTIVITY_SINGLE_TOP and some "extra" that describes what FolderActivity should do. In FolderActivity override onNewIntent(), read the passed Intent parameter and use it to determine what method to call in FolderActivity. Because the Activity was launched withIntent.FLAG_ACTIVITY_SINGLE_TOP, Android won't create a new instance of the Activity, it will just callonNewIntent()` on the existing instance.
Have FolderActivity set a public static variable of type Activity to a reference to itself in onCreate(). MainActivity can then call a method on FolderActivity by doing something like FolderActivity.activityReference.doSomething()
Method 3 is not the preferred method, since you need to make sure that you set the public static variable to null in FolderActivity.onDestroy() and there are other concerns (timing issues, memory leaks, etc.) that need to be dealt with properly.
NOTE: You probably don't want to call onOptionsItemSelected() directly. This method is called by the Android framework when an options item is selected by the user. You should call directly the method that actually does something, not this framework callback method.
